About Nutrition & Diet Calculators
Hit your nutrition goals with free diet calculators. Estimate daily calories and TDEE, plan macros, set a calorie deficit, and convert or scale recipes to the right number of servings.
These are some of Calcshark’s most-used tools. From a recipe converter that rescales ingredients to a calorie calculator that sets a daily target, they turn diet guidance into specific numbers.
Frequently Asked Questions
How many calories do I need per day?▼
The calorie and TDEE calculators estimate your daily needs from your age, sex, weight, height, and activity level, then adjust for weight-loss or gain goals.
How do I scale or convert a recipe?▼
The recipe converter and scaling calculators multiply every ingredient to match your target servings, and convert between cups, grams, and ounces.
What is a calorie deficit?▼
A calorie deficit means eating fewer calories than you burn, which drives weight loss. The deficit calculator sets a daily target for a chosen rate of loss.
